Preparing to park into a parking space in an off street parking lot the vehicle forcefully and rapidly accelerated on its' own and crashed into a fence. I was not accelerating. I attempted to stop the car using the brakes but they did not engage quickly enough to stop the rapid, forceful, and without warning acceleration. Buick has been contacted about the defect. Buick ran extensive diagnostics on the car and denies there is a defect. Police came to the scene and advised that given the 2 other incidents that I have experienced, the car is unsafe to drive given potential damage to others. A police report was filed.

When pulling into parking space the car rapidly accelerated on its' own and crashed into the car in the next parking space. I did not have my foot on the gas, the car was simply idling. The acceleration was so rapid that applying the brake was useless.

While the vehicle was driving, there was a loss of power, at that moment sparks was seen emanating from under the hood, then the vehicle completely stopped running. Once pulled over smoke was bellowing out from the hood and subsequently ignited into flames. Fire department was dispatched and fire was extinguished. The vehicle was towed away and is still at the tow yard. The tow operator, based on visual inspection stated the fire did start in the engine compartment and spread to the fire wall, totaling the vehicle.

The oil consumption in the car is horrible, I have to atleat add oil in my car about 5 time in between oil changes, and my oil changes are done regularly, ive also have the issue of my oil and gas mixing, I did take it to the shop once and they fixed a recall that was involved with high pressure fuel pump, but im guessing they didnt fix the issue once that repair was done like they said it would.

I noticed that the car was resisting acceleration a little bit, have 48,545 miles on it and took it for oil change with fuel injection cleaner and full tank of good gas. Got on highway and the acceleration died completely and no gas was getting through, like flooring it in neutral. Pulled off the side and it restarted but continued dying along the way if I try to accelerate.

Reference the below background information on gm's l4 - 2.4l 4 cylinder engines: please reference document id: 4821148 #12313d: special coverage - engine balance chain and fuel pump - (june 6, 2017) this special coverage bulletin was provided by my mechanic at midas from the http://alldatapro.com website. Special extended warranty repairs are supposed to be covered via this bulletin for 120,000 miles or 10 years for gm vehicles that have the l4 engine including the 2011 buick regal. My 2011 buick regal is definitely exhibiting all symptoms / problems that are well known with the general motors l4 - 2.4 l four cylinder engine. See information below about oil consumption and engine performance symptoms: https://www.msn.com/en-us/autos/research/seven-engines-to-avoid-like-the-plague/ar-aavz7vm#page=3 I am a former gm powertrain division engineering / salaried employee where I had a 20 year career background with engines and transmissions. The l4-2.4l engine is a known safety hazard as the engine can fail while under normal operation on a highway or city street with potential catastrophic results. Even with the mechanic oe bulletin referenced above, gm refuses to cover expenses for permanent repairs for the 2011 buick regal. Instead dealership customer service representatives are instructing vehicle owners to just add oil frequently. (note: the low oil indicator is also defective.) please also reference the class action law suit below: https://www.classaction.org/media/berman-et-al-v-general-motors-llc-joint-notice-of-settlement.pdf gm corporation customer service, professional mechanics, and gm's dealership network (buick and cadillac) all are fully aware of the catastrophic safety consequences that this engine poses to the general public; yet, a comprehensive recall and appropriate extended warranty coverage is being denied.
